Earthwool® External Wall batts are a new generation of softer, safer and more environmentally friendly Glasswool insulation. Although the product is primarily designed for use in external walls it can also be used for internal walls to reduce sound transmission from room to room. High Density (HD) and Super High Density (SHD) External Wall batts with increased density and lower thermal conductivity to maximise energy savings are also available in the range.
Earthwool® Internal Wall batts are available in a range of densities for metal and timber frame construction, providing options for your individual requirements. This specialist acoustic range of insulation products is available in Basic Performance (11 kg/m³), Ultra Performance (14 kg/m³), High Density (17 kg/m³, 20 kg/m³ and 27 kg/m³) sound absorbing performance levels.
The Earthwool® External and Internal Wall batt range includes a selection of R-Values to provide builders, designers, installers and DIYers the opportunity to choose the best thermal performance for their project. Earthwool® External and Internal Wall batts will also absorb the transfer of unwanted sound from outside to inside the home. In addition to sound absorption, Earthwool® External and Internal Wall batts will improve the thermal comfort and energy efficiency of the building in which they have been installed thus keeping it cool in summer and warm in winter. Super-soft to handle and install, Earthwool® is made using up to 80% recycled glass and with ECOSE® Technology, a sustainable, bio-based binder that contains no added formaldehyde.
